Canto Bight by Saladin Ahmed, Rae Carson, Mira Grant, and John Jackson Miller
Canto Bight is the galaxy's most luxurious Casino City, and one of the settings of the The Last Jedi movie. In this book, four star authors each contribute a short novella about the lives of the people living in and visiting this city, and the gambles they must take to survive in a world where beauty is only a facade.
The stories are based on settings and background characters from The Last Jedi. Some of them ended up getting cut from the actual film, but it's a really fun read anyway.
